The Xbox Series X is fantastic at running backwards compatible games with unlocked framerates, and 2008's Grand Theft Auto IV on the Xbox 360 happens to be one of those titles - running at a smooth 60FPS on the system.
However, as fantastic as the performance is, one Redditer discovered recently that the game's final mission becomes near-impossible to complete as a result, which requires you to repeatedly tap the A button to climb into a chopper. The problem? Seemingly, the framerate is now too high to register enough taps of the button correctly.
This Reddit thread is filled with comments suggesting potential solutions, and the original poster eventually managed to finish the mission by activating copilot mode on the console and using vibrating toothbrushes to rapidly press the A buttons on both controllers. Nope, we're not making this up!
"IT WORKED. I couldn’t stop laughing. You have to have the head of the toothbrush on the controller so the a button is pressed down, but literally no further pressure on it. The vibration will do the rest of the work. I’ve probably done some lasting damage to the controllers but hey! I’ve completed a game I started 10 years ago!"
It's worth noting that PC players have been reporting issues with this mission for some time, and it's reportedly even a problem on Xbox One X, so you might have run into it before. The best solution is to boot up your old Xbox 360 and finish the game there, but at least there's a potential workaround if you don't have access to one!
